The refill stations in the “Compact” series are
of the semi-soundproofed type (model
MCH 13-16/ET) (Fig. 2) (model MCH 26-32/ET)
(Fig. 1).

The air circulating around the compressor, which does not contain any harmful fumes, is taken into the
intake filter and introduced through the intake valve into the cylinder of the first stage where the first
compression takes place.
A part of the heat produced in the compression is dissipated by the flow of air created by the fan through
the head and relative valves, piston, cylinder, monobloc and lubricating oil; the heat remaining in the
compressed air is dissipated in the long piping connecting one stage of the compression to another and
which acts as a radiator; the temperature at the hose outlet is just a few degrees higher than that of the
environment.
The operating temperatures of each stage are: at the pipe connection that goes to the intake cylinder:
about 15-20 °C above the environmental temperature (it feels warm to the touch), to the pipe connection
that starts from the head (from the discharge valve), about 80-100 °C.

Technical description
Model MCH 13-16/ET is fitted with a compressor
(Fig. 4), while model MCH 26-32/ET is provided
with two compressors (Fig. 3), which enable the
latter to refill up to four cylinders at the same time
(in the standard version).
All the compressors fitted inside the refill stations
are of the high pressure type with forced air cooling
and 3 stages of compression.
